I am a Volunteer and I have been answering questions here for 8 years, usually when logged in under my timethief account. That means I date back to the time when there was a single Support Staff.
Never ever, not even once in the over 3000+ threads I have responded to has what you described ever happened to me or to any other WordPress.COM blogger that I am aware of. The reason for that is clear. Every blog is an independent website and no matter how many blogs are registered under the same username account they remain independent. What's done on one blog has absolutely no effects of any kind whatsoever on any other blogs registered under the same username account.
We do have a forum code of conduct on these peer support forums http://en.forums.wordpress.com/topic/wordpresscom-forums-code-of-conduct?replies=1
Also note what's below every comment box in every thread here:
We love positive and productive discussions, so please keep comments on the topics at hand and not on other members of the community. Thanks!
You posted this:
Please do not write if you cannot resist using abusive language.
Apparently, you are not aware that posting anything of that nature into any thread here means two things an both look bad on you. (1) You are leaping to the conclusion that others will be abusive (2) by posturing as victim.
